Hi everyone! I have the following problem at hand, which is probably trivial but way beyond my ability to design circuits.
I have a very low current DC voltage coming from a Cockcroft-Walton Multiplier, that I would like to use to intermittently supply at least T seconds of 3.3±0.2 V DC to a micro-controller while guaranteeing its requirements for peak current.
It feels to me that, at least in theory, I should be able to charge a (big enough) capacitor for long enough and then discharge it in a controlled way such that I can guarantee T seconds of operations to the microcontroller.
I'm happy to wait indefinetely between each discharge to make sure that the capacitor charges despite the weak input current, but I'm by no means able to understand how to design a circuit like that.
Any hint would be appreciated!
